Lawmakers—especially Democrats—have a historic opportunity. Will they seize it?

Congress right now has a historic chance—really, it could wind up in the history books next to the stopping of FDR's court-packing scheme in 1937—to hold back ObamaCare. Congress can delay it, or pass a law mandating or allowing insurance companies to continue insuring everyone they just threw off coverage. Heck, they could try to vote now, under new conditions and with the American people behind them, to repeal the whole thing.
